KIRO-TV

THURSTON COUNTY, Wash. — In a test that’s never before been done in Washington, KIRO 7 Eyewitness News had volunteers smoke marijuana and then put them behind the wheel to show what stoned driving looks like and the danger on the road.

As a consultant prepared the marijuana smoking lab, three volunteers each took a practice run on a course set up by the Thurston County Sheriff's Office that was designed to test their basic driving skills.

In the car with them was Cascade Driving School instructor Mike Jackson, who had a brake on his side of the vehicle for safety.
